<span>It took sergio 3 hours to read 7 chapters of a book. If he continues reading at a constant rate and the chapters are similar in length, how many hours will it take sergio to complete the entire book if it is 15 chapters long?
Let’s first solve Sergio’s rate of reading
=> 7 chapter for 3 hours
=> 3 / 7 = .43 hours
Unit rate = 1 chapter for .43 hours
=> .43 hours * 15 = 6.43 hours,
Thus, he can finish reading 15 chapters for 6.43 hours.,</span>
